Specification of Letters Patent.

Patented Jan. 2, 1906.

Application filed April 5, 1905. Serial No. 253,942.

T0 a/ZZ whom it may concern;

Be it known that I, SYLVEsTER S. HAWLEY, a citizen of the United States,residing at Centralia, in the county of Marion, State of Illinois, haveinvented Certain new and useful Improvements -in Multiple-BoltMechanism, of which the following is a specification, reference beinghad therein to the accompanying drawings.

This invention relatesto amultiple-boltoperating mechanism, andparticularly to a construction whereby a plurality of springactuatedbolts or latches are simultaneously operated by a movement of one ofthem.

The invention has for an object to provide an improved construction andarrangement of the parts by which in the operation of a bolt otherlatches or bolts disposed at different points may be simultaneouslymoved and the operating-bolt secured and held in its adjusted position.

Other and further objects and advantages of the invention will behereinafter set forth and the novel features thereof defined by theappended claims.

In the drawings, Figure l is an elevation showing the invention appliedto a door, and

Fig. 2 a detail perspective of the operatingbolt for the mechanism.

Like letters of reference refer to like parts in both figures of thedrawings.

The letter A designates a door or other similar structure to which thebolts or locking mechanism B may be applied and coperate witha suitablekeeper B upon the frame A of the door. These bolts B are of anypreferred construction in common use, but preferably spring-actuated,and the bolt at the top of the door is connected with the operating-boltat thebottom of the door by means of a chain or other suitableconnection B2, extending therefrom to a rod C, carried by the lever C2of the bolt C, whichbolt is pivotally mounted at C3 within any suitableform of casing C4. The bolt B at the side of the door is connected withthe chain B2 by means of a supplemental chain B3, passing over a pulleyB4 and connected at B5 with the main chain B2. The object of thissupplemental chain is to secure a direct pull in releasing the bolt B atthe side of the door.

The bolt C is normally thrown downward into contact with the floor or asuitable aperture therein by means of a tension-spring C5, whichsurrounds the post C, carried by the lower bolt, and is disposed betweenthe casing and the upper face of the bolt. The bolt is provided beyondits pivot with a latch-plate C7, pivotally mounted at C8 in the free endof the bolt and adapted to oscillate laterally of the bolt in order toengage notches or recesses'C, formed in an end wall C10 of the casing C,these notches or recesses being connected by a slot to permit a downwardmovement of the lever end of the bolt C when the latch-plate C7 is inalinement with the slot.

In the operation of the invention it will be seen that all of the boltswill be released when the latch-plate carried by the lower bolt isdepressed and its spring placed under tension, in which position it maybe retained by a lateral movement of the latch-plate in the engagementwith the lower notch carried by the casing. The door is now free to beopened and may be held in a partially-opened position by releasing thelatch-plate, so that the bolt C will be thrown downward tofrictionallyengage the floor. When the door is closed, with the parts inthese positions, the several bolts engage their proper sockets, and thedoor is thus held, while any operation of the lower bolt by tension uponthe connecting means may be obviated by engaging .the

latch-plate with the upper recessin its casing, as shown by full linesin Fig. 2. It will thus be seen that the lower bolt embodies means forsimultaneously operating those connected therewith and for holding themin their locked or unlocked position.

It will be obvious that changes may be made in the details ofconstruction and configuration without departing from the spirit of theinvention as defined by the appended claims.

Having described my invention and set forth its Inerits, what I claim,and desire to secure by Letters Patent, is

1. In a device of the class described, a pivoted angular operating-boltprovided with a lever at one side thereof, a locking-bolt removed fromsaid operating-bolt, a rod extending from said lever, a connectionextending from the locking-bolt to the rod upon the lever of the pivotedbolt, a fixed plate, and a pivoted latch-plate carried by the lever endof the operating-bolt to engage said fixed plate.

2. In a device of the class described, an angular operating-bolt pivotedintermediate of its ends, a casing within which said bolt is disposed, apost disposed upon said bolt at one side of its pivot, a springsurrounding IOO IIO

to engage a `fixed plate, a connecting-rod eX- tending from the leverend of said b olt through said casing, a bolt disposed at a distancetherefrom, and a flexible connection between said rod and locking-bolt.

' In testimony whereof I my signature in presence of two witnesses.
